Google wants businesses to make Google Apps their primary productivity suite, so the company is recruiting at full swing today with a new blog post that discloses a few stats about its energy efficiency.

Google Apps is a Google service that features several Web applications like traditional office suites. The services vary per edition but generally include Docs, Gmail, Calendar, Talk, Sites, Groups, Video, and Marketplace. Its popularity among businesses and academicians is rapidly increasing due to enhanced sharing features, accessibility, and cost.

According to Senior Vice President for Technical Infrastructure Urs Hoelzle on the Official Google Blog:

At Google, we’re obsessed with building energy efficient data centers that enable cloud computing. Besides helping you be more productive, cloud-based services like Google Apps can reduce energy use, lower carbon emissions and save you money in the process. Last year, we crunched the numbers and found that Gmail is up to 80 times more energy-efficient than running traditional in-house email. We’ve sharpened our pencils again to see how Google Apps as a whole—documents, spreadsheets, email and other applications—stacks up against the standard model of locally hosted services. Our results show that a typical organization can achieve energy savings of about 65-85% by migrating to Google Apps.

Hoelzle further explained how lower energy use equals less carbon pollution. The executive supported this statement with an anecdote about the U.S. General Administration. It switched to Google Apps for Government to save $285,000 annually at a 93 percent cost reduction, and it reduced energy consumption by 90-percent and carbon emissions by 85-percent.
